Sure, I can help you create a simple game using JavaScript and pictograms in a single HTML file. The game will be playable on a smartphone. Here's an example implementation:
This is a simple game where the player's goal is to shoot the target person by aligning the car with the target and pressing the "Shoot" button. The car, gun, and person pictograms are displayed on the screen. The player can move the car left or right using the "Left" and "Right" buttons to align it with the target. When the player clicks the "Shoot" button, a message will appear indicating whether they hit or missed the target. The game will reset after each shot.
Please note that this implementation is a basic example and can be expanded upon with additional features and gameplay mechanics as desired.
